Application September 11, 1952, Serial No. 309,101

1 Claim. (Cl. 51181) My invention relates to sharpening devices for safety razor blades, and more specifically to improvements in combination bones and strops for such blades.

The primary object of my invention is to provide a simply constructed, inexpensive sharpening device embodying a holder for a bone and a strop especially designed for grasping with comfort in one hand and for spacing a hone and strop above a surface upon which the holder is laid when not in use.

Another object is to provide a sharpening device for the above purposes embodying a holder for a hone and a strop constructed and arranged for easy and quick replacement of the hone and strop when the same become worn.

Other and subordinate objects within the purview of my invention, together with the precise nature of my improvements, Will be readily understood when the succeeding description and claim are read with reference to the drawing accompanying and forming a part of the specification.

In said drawing:

Figure l is a view in perspective of my improved sharpening device in the preferred embodiment thereof;

Figure 2 is a view in plan;

Figure 3 is a view in longitudinal section taken on the line 33 of Figure 2;

Figure 4 is a fragmentary enlarged view in transverse section taken on the line 44 of Figure 2; and

Figure 5 is a fragmentary enlarged view in longitudinal section taken on the line 5-5 of Figure 2.

Referring to the drawing by numerals, the sharpening device of my invention comprises a holder 1 for a hone 2 and a strop 3, of a suitable size to be held in one hand.

The holder 1 comprises a thin flat plate 4 of oblong rectangular form, and tubular side members 5 on said plate 4 for supporting the plate 4 on a surface in elevated position with either side of the plate uppermost, the side members forming comfortable hand-grips by means of which the holder may be held between the thumb and fingers of one hand without pinching the same. The plate 4 and side members 5 are secured together with the plate 4 diametrical to both side members 5 so that the plate will be elevated above the surface by said side members for a substantial distance. For securing the plate 4 and side members 5 together, each side member 5 is provided with a longitudinal slot 6 having a pair of spaced marginal flanges 7 inside the member, and the side edges 9 of the plate 4 are extended through the slots 6 and fitted between the flanges 7 of the pairs, with the plate 4 spot-soldered, as at 10, to said side members 5 at the ends of the plate 4 and side members 5. The plate 4 and side members 5 are formed of lightweight, thin-gauge, comparatively strong metal, such as aluminum.

The hone 2 comprises a composition or stone slab on one side of the plate 4 of rectangular form and the same length as said plate 4 but slightly narrower to fit between the side members 5 clear of the solder 10. The hone 2 is detachably secured to the plate 5 by a pair of extension lips 11 at each end of said plate 4 spaced apart upon opposite sides of the longitudinal center of said plate and which are bent over end ledges 12 on the hone offset from the face of the hone, so that the lips 11 will not interfere with the honing operation. The strop 3 is of the same size and shape as the hone 2 and is secured at its ends to the other side of the plate 4 by a pair of end lips 14 on said plate 4, between the lips 11 of the pairs, bent over and pressed into the ends of the strop 3. The strop 3 may be formed of leather or composition, as desired.

It is to be noted that both the hone 2 and strop 3 are of less thickness than the radius of the side members 5 to be supported by the holder 1 clear of any surface on which the holder is laid.

The manner in which the invention is designed to be used will be readily understood without explanation. It may be explained, however, that by bending the lips 11, 14 outwardly of the plate 4, the hone 2 and strop 3 may be detached from the plate 4 and then replaced by new ones which may be quickly and easily secured to the plate 4 by bending the lips 11, 14 back in place.

The foregoing will, it is believed, suffice to impart a clear understanding of my invention both as regards the structure and advantages thereof.

Manifestly, the invention, as described, is susceptible of modification without departing from the inventive concept, and right is herein reserved to such modifications as fall within the scope of the appended claim.

Having described the invention, what is claimed as new is:

A sharpening device for safety razor blades comprising an oblong rectangular plate having tubular members at opposite longitudinal edges thereof, said plate being attached to said members in diametrical position relative thereto to be supported on a surface by said members in elevated position with either side of the plate uppermost, said tubular members providing cornerless hand grips, a hone on one side of the plate, and a strop on the other side of the plate, said hone having reduced end ledges thereon extending therefrom and said plate having end pairs of extension lips thereon bent to one side thereof over said ledges to secure the hone to said plate, said plate having end lips thereon bent over to the other side thereof between the lips of the pairs and pressed into the strop to secure the strop to the plate.
